Key: A 2-sided Mc Nemar’s test was used to compare results to baseline (pre-treatment). Significant differences are denoted as: ***(p<0.0005); **(p<0.005); *(p<0.05).

¥ 22 and 44mcg tw groups combined. The combined group includes the full history of patients who may have switched (without interruption) between low and high dose IFNB-1a(sc) and vice versa, therefore in some instances simple addition of the 22mcg and 44mcg groups does not equal the combined figures (¥).

Note: Addition of columns: ‘pre-treatment’ figures + ‘de novo during treatment’ figures ≠ ‘total during treatment;’ as some patients with a missing baseline may have had elevated aminotransferases and hence would only be included in the ‘total during treatment’ column.
